Bc ilv hmm/'n diet wel-lem ,N M. llo-EL- ol' lTool; and Stilte oi illinois, lieve in- .i useful .improvement in Shower-Bath Cocks, of which ng is i. speciiication. union relates to improvements in shower-bath cocks. oi our niveniion is to provide a sliowenhaili cock. of e, simple,

durable construction for conlioc or eold water and hot i avaler inixed to shower-balli or its Lennon-pipe, Which Awill loe simple in opoiii and capable oli being readily manipuf, by chil-.dien and other persons having io familiarity with shower-baths and possibility of lioii Water being sudilj: riirned on, a.v d thus scalcling, endanor injuring l yaerson.

'iventi or con sits in the means we em- -ly o .omplish this object or say, it consists in a three- Aor case fnrnisl l. with one Wili .Le liotfs; .iger-su ppl y nipple eonnecing' v-.v'ith the pipe, end 'third nipple connecte civernconnection pipe, valvefoj opening and closing the with erich of seid pipes, e nhie reciprocating sleeve carryingr '-vconneciion valve end provider s or inclines ad apted to engage and i iist the cold-Water valve, afterward by :er inoveinenl, to open the liot-water llicn lijvf .Still further movement to .it the closingl of the cold-Water he liet-Meter valve open,

`n nd loins J. (linmean citizens of the -.iilrri firmes, residing in Chicago, in the open the showerclie cold-Water valve lille screw-mein will er 'valve and maintain also open, 'Lluis deliver- 'l to the shower,

he screwin;r

ie closid cold Water i l so that holA water l l 1 l l l l l l ing of the cold-Water valve, and thus causo hot water only to he delivered to the shower, 5 5 so that the hoty water cannon be turned on at all Witlioi'l first turningon the cold Water andv only cannot. he delivered to the shower at all Without Afirst delivering hot and cold water mixed and ishing and finally cutting olf the Coldwater supply, and thus practically ieiiioviiigl all danger of scalding orinj nry, however ignorant or iinsliilled the person maybe in tlieinanipw lation of the shower.

Our invention also consists in the novel construction ol' parts and devices and in the novel combinations or' parts and devices l1erein shown and described.

In the accompanying drawings, forming a 7o part of this specilication, Figure l is a central vertical section of a non-scolding showercock embodying our invention. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is a horizontal section on line 3 301: Fig. 2. Fig. 4 is a section online 4 -1 of Fig. Fig. 5 is a detail view of the non-rotatable reciprocating valve-operating sleeve, and Fig. 6 is a. deail end view of said sleeve.

.ln the drawingsI Arepresenlis thelnein shell 8o or case of the cock, the saine having a screW- threaded nipple A forl connection with the liot-water-supply pipe B and a screw-threaded nipple A2 for connection with the cold Water-supply pipe C, and a nipple A3 for connection with the shower pipe or connection l). The valve-shell A is furnished with a valveseat a for the discharge or shower-connection valve E, a valve-seal; fr for the'cold-Water valve F, a valve-seat o for the hot-Water 9o valve G, and also With integral Webs a3 al, having holes therethrough for guiding and supporting the valve-stems fg of 'the valves F G. The valves F G open against the Waterpressure, and their Steins f g are preferably 95 furnished With sprinffs f g', bearing against the shoulders or col ars f2 g2 on the velvestenis to aid the Water-pressure in holding the valves normally' closed:

l is a 1ion-rotatahle reciprocating valvc. loo operating sleeve, the seine carrying,r the dis charge shower-connection valve E directly thereon and being preferahl y provided with an annuler Sfinge li to receive said shower or .'liseliarge valve E. The non-rotating recip 1o 5 ro sleeve H is provided with e cani or ingradually diinin- 6o opened, and a screw-stern for reci rocating said sleeve whereby cold Water is st delivered, then cold and hot Water mixed, and hot Water can only be delivered alone after rst turning on and off the cold. Water, said reciprocating sleeve havin guides or lan es thereon, and the valve-shell having a gui epin engagin said guide-flanges on the sleeve to prevent t e sleeve from turning, substantially as specified.

5. ln a non-scalding shower-bath cock, the combination with a -valve-shell, of a hot- Water valve, a cold-Water valve, a non-rotatable reciprocating sleeve provided with cams or inclines thereon engaging the stems of said valves for operating the same, the cam for incline for operating the cold-Water valve being in advance of the one for operating the hot-Water valve, and having a reverse incline to permit the closing' of the cold-Water valve after the hot-,Water valve has been opened, and a screw-stem for reci rocating said sleeve whereby cold Water is st delivered, then cold and hot Water mixed, and hot water can only be delivered alone after first turning on and off the cold Water, and a shower-controlling valve operated by said eciprocating sleeve, substantially as speci- 6. In a non-scalding shower-bath cock, the combination With a valve-shell, of a reciprocating hot-Water valve, a reciprocating cold- Water valve, and a non-rotatable sleeve reciprocating between and at right angles to said hot and cold Water valves and provided With cams or inclines thereon engaging the stems of said valves for operating the same, the cam or incline for the cold-Water valve opening said f valve before the hot-Water valve is opened, and a screw-stem for reciprolating said sleeve, substantially as speci- 7. In a non-scalding shower-bath cock, the

combination with a i,valve-shell, of a reciprocating hot-Water valve, a reciprocating cold- Water valve, and a. non-rotatable sleeve reciprocating between and at right angles to said hot and cold water valves and provided with cams or. inclihes thereon engaging the stems of said valves for operating the same, the cam or incline for operating the cold- Water valve opening said valve before the hot- Water valve is opened, and a screw-stem for reciprocating said sleeve, and means for preventing said sleeve frointurning, substane tially as specified.l

8. In a non-scalding shower-bath cock, the combination with a valve-shell, of a reciprocating hot-water valve, a reciprocating cold- Water valve, and a non-rotatable sleeve reciprocating between and at right angles to said hot and cold Water valves and provided Iwith cams or inclines thereon engaging the stems of said valves for operating the same,

the cam or incline for operating the cold-i155 Water valve opening said valve before the hot- Water valve 1s opened, a screw-stern forreciprocating Ysaid sleeve, and a stationary screw secured to the valve-shell an'd coperating with said screw-stem, substantiallyas specified.

9. A non-scalding cock, comprising'inA combination a valve-shell, a hot-Water-ei1p-- ply valve, a cold-water-suppl valve, a Areciprocating slide ca g e" disch e4 75 valve and provided Wit cams or inclines or operating the cold and hot Water valves succession, and a rotary screwvstem for re` ciprocating said valve-operating slide, subiw stantially as specified. *18o 10.
